In the States, the BlackBerry Storm 9530 had its' last official upgrade in June, as we reported. The version released was 188.8.131.52. Since then, a leaked, unofficial version of OS 184.108.40.206 was released. Power users of the Storm are hoping it won't be too long before an official 5.0 version of the BlackBerry OS is launched for the Storm because it is thought that tabbed browsing will be one of the features available on that build. Many expect a 5.0 OS upgrade for the Storm to come around the same time that the Storm 2 will be released in October/November. The sequel to the first touchscreen 'Berry will be equipped with an OS build beginning with the number 5.
